The Flakpanzer 341 - was conceived FlaKPanzer V. by Rheinmetall-Borsig began developing this antiaircraft vehicle in December 1943. Codenamed the "Coelian" I hadn’t really recalled seeing in any pics I had seen from WWII before – and with good reason, a completed version never existed! A mock up did – the picture of which is above. This AA tank though did make it past the mock up stage, but I think it would have been a great vehicle for the purpose – the Panther chassis and two fully traversable twin 3.7cm FlaK 43 cannons mounted in a fully armored turret which could fire straight upwards would have given the Allied "Jabos" something to think about in their mud moving missions.
